Thunderous Business takes place in the same universe as Devilish Business: a universe in which belief is power. You play as a recent college graduate who has a not-so-chance-encounter with Zeus, a god dying from lack of belief. He offers you the mantle – and powers – of High Priest in a last ditch attempt to revive his following and save him from eternal oblivion. As High Priest, it is your job to spread the faith throughout your city, and maybe even beyond.
